Find the Right Toptech Size Furnace Filter

Avoid this Common Mistake and Get the Correct Furnace Filter Size

The Most common mistake made when ordering filters is ordering the wrong size furnace filter. This is because the size on the filters is not necessarily the actual size of the filter. Filters are sold by nominal sizes which are rounded sizes and usually vary by brand. You can usually Find the Size of Your Air Conditioner filter right on the size of the frame of the filter. The Picture of this 12x12x1 inch air filter has the Nominal size which is the size by which air filters are generally sold. On the right of the filter, it also includes the actual size of the filter which are the true measures dimensions of the filter by length width and depth. See air filter image:

If there is no size on your current AC filter, you can measure the length, width, and depth of the filter and the filter to find the Actual Size of your filter with the Corresponding Furnace Filter size in the Furnace Filter Size(Nominal Size) Chart.
